"I don't think I changed anything of what I said because there was nothing to change", Trump Jr. told reporters after the Senate interview.

The appearance by Donald Trump Jr before the Senate Intelligence Committee follows a dispute that made headlines last month when the president expressed surprise that his son was being hauled before Congress for a second time as part of the panel's probe. But Trump Jr. told the Judiciary panel he was only "peripherally aware" of the real estate proposal.

After his interview, he maintained he had been consistent. I'm glad this is finally over and we're able to put final clarity on that.

The senators also were expected to question Trump Jr. about a June 2016 meeting he and campaign advisers Paul Manafort and Jared Kushner held at New York's Trump Tower with a Russian lawyer.

"I don't think I changed anything of what I said because there was nothing to change".

The Trump team had initially tried to cover up the meeting, providing conflicting stories about its goal and what happened.

Mueller's report did not find enough evidence of conspiracy between anyone in the Trump campaign and Russian Federation, but lawmakers still have questions about the possible times Mueller found the president may have obstructed justice.

On Wednesday, Trump Jr said he provided "clarification" to the intelligence panel, and pointed out that Cohen himself is now serving a prison sentence for campaign finance violations and lying to Congress.

The interview had been expected to focus on a Moscow Trump Tower project and a meeting with a Russian lawyer who claimed to have information helpful for Trump Sr.'s 2016 presidential campaign.

The report did not find any clear evidence to charge members of Trump's campaign with conspiring with Russian Federation, but neither did it exonerate the president of obstruction of justice. Burr told The Associated Press last month that he hopes to be finished with the investigation by the end of the year.

Democrats are debating among themselves whether there is enough evidence and political space to pursue an impeachment motion against Trump.

For two years, the committee's Republicans and Democrats have been quietly investigating Russian interference in the United States presidential election of 2016. Ted Cruz, said there was "no need" for the subpoena.

As one of the longest-serving Trump aides during the campaign and in the White House, Hicks had a front-row seat in numerous incidents the Democrats are investigating.
